Definitions

  • ABSTRACT 0F THE DISCLSURE This invention relates to a hydroelectric machine set having a housing adjoining the runner of the hydraulic machine, fully submerged in the operating water and enclosing the electrical machine, in which housing are also situated the two bearings of the shaft carrying in overhung fashion at its one end the runner of the hydraulic machine, and at its other end the rotor of the electrical machine.
  • the housing has, according to the invention, two separations, each extending in a plane which is substantially perpendicular to the axis of the machine, and a radially removable intermediate piece is provided between these planes, and contains the stator of the electrical machine with end connecting iianges extending substantially to the respective plane of separation, the rotor of the electrical machine, the shaft bearing situated next to the electrical machine, as well as its bearing bracket connected to the stator or to a connecting flange, as well as a shaft portion extending to the runner-side plane of separation, which shaft portion is detachably connected to the remainder of the shaft by a rigid coupling.
  • FIG. l shows a vertical axial section through a machine set
  • FIG. 2 shows a corresponding section through another embodiment
  • FIGS. 3 to 6 show portions of FIG. l on a larger scale
  • FIG. 7 shows a section on the line VII- VII in FIG. 1,
  • FIG. 8 shows a section on the line VIII-VIII in FIG.
  • FIG. 9 shows a section on the line IX-IX in FIG. l.
  • the hydroelectric power plant shown in FIG. 1 has a foundation 1 with an operating water duct 2, in which is situated a housing 3, fully submerged in the operating water and enclosing an electrical machine 4. Also situated in the housing 3 are the two radial bearings 5 and 6 and the axial bearing 7 of a shaft 3 carrying in overhung fashion at one end the runner 91 of the hydraulic machine 9, situated in the operating water stream and at its other end the rotor 41 of the electrical machine 4, also in overhung fashion.
  • the housing 3 has two separations 10, 11, each of which extends in a plane of separation perpendicular to the axis of the shaft 8. Situated between said two planes of separation 10, 11 is a radially removable intermediate piece 12, containing the stator 42 of the electrical machine 4, with end connecting anges 101 and 111, extending to the respective plane of separation, the rotor 41, the radial bearing 6, situated next to the electrical machine 4, and the axial bearings 7, together with the bearing bracket 13, which connects the bearings 6, 7 to the connecting flange 111, i.e. to the stator 42.
  • the intermediate piece 12 furthermore contains a shaft portion 81, which carries the rotor 41, is journalled in the bearings 6 and 7 and extends to the runner-side plane of separation. It is detachably connected to the remaining shaft part 82 by a rigid coupling 14.
  • the wall 15 of the intermediate piece 12, situated between the two planes of separation 10, 11, is a component of the stator 42 of the electric machine, and the connecting flanges 101, 111 are flanges of the intermediate piece 12 at the same time.
  • the wall 15 forms the supporting ring of the stator 42 of the electrical machine 4.
  • the flanges 192 and 112 of the housing parts 31 and 32, which anges adjoin the connecting flanges 101 and 111, are additionally held by tie rods, anchored in the walls of the operating water duct 2 and engaging the housing 3 substantially tangentially, so that the housing 3 and the stator 42 of the electrical machine 4, which stator is situated in the intermediate piece 12, are securely and non-rotationally held in the foundation 1.
  • the tie rods not shown, extend inside the ribs 16 and 17, as indicated by the chain lines (see also FIG. 9).
  • Spaces 19 and 20, wetted by the operating water, are left free between the ribs 16 and 17 and the intermediate piece 12.
  • the space 19 only includes the immediate surrounding of the intermediate piece 12; the space 20 extends over the full height of the rib 17 and adjoins an opening 21 connecting the operating water duct 2 to the platform 22 of the foundation 1.
  • the space 20 and the opening 21 occupy the region bounded by the planes of separation 10, 11.
  • the space 26 extends over the full width of the rib 17, and the opening 21 extends over a range exceeding somewhat the diameter of the intermediate piece 12.
  • the shaft 8 is surrounded by a tubular shell 25, containing an oil bath, which extends from bearing 5 to bearing 6 and is composed of a number of individual parts. It has a separation, situated in the runner-side plane of separation 11 of the intermediate piece 12.
  • a gearwheel 26 is mounted on the shaft 8 for driving a pendulum generator 27 and auxiliary units, not shown.
  • a sleeve 28 serves for introducing the control oil ducts 29 into the shaft 8 for the runner blade pitch adjustment.
  • an exciter 30 having a rotor 301, fast on the shaft piece 81, and a stator 302, connected to the connecting flange 101 (FIG. 5) as well as generator brakes, not shown, are arranged in the intermediate piece 12, also within the space bounded by the two planes of separation 10, 11.
  • the separation is provided with a movable flange ring '103, arranged between the connecting flange 10'1 and the flange 102 of the front housing part 31, as shown more clearly in FIG. 3.
  • the flange ring 103 is centered in the flange 102 and in the connecting flange 101, and after disconnection of the screws 23, 24 connecting it to the parts 101, 102, it can be moved axially to the left in the drawing.
  • connection between the intermediate piece 12 and the runner-side housing part 32 is also disconnected by unscrewing the screws 31 connecting the connecting flange 111 to the flange 112 (FIG. 4).
  • the intermediate piece 12 is then shifted axially to the left in the drawing until the connecting flange 111 has moved out of the centring means, centring it with the flange 112.
  • the gap between the parts 101, 102 is wider, for this purpose, than the width of the centring means between the parts 111, 112 and 81, 82.
  • the intermediate piece 12 and the parts contained in it can now be moved radially of the axis of the machine set through the space 20 and opening 21. It is thus possible to make the length of the dam cross section, in the direction of flow of the operating water, particularly the width of the crane track and platform, substantially shorter, resulting in a considerable saving of building and machine costs.
  • the spaces 19 and 20, wetted by the operating water and left free within the rib profile, are limited from the flow space of the operating water duct 2 by guide plates 32, 33.
  • the lopening 21 is closed by a cover 34.
  • the rib 17 has two manholes 171 and 172, connecting the housing parts 31 and 32 to the platform 22.
  • the machine set according to FIG. 2 differs from that according to FIG. 1 by the formation of the housing parts 31 and 32 and the ribs 16 and 17 in concrete construction.
  • the flanges 102 and 112 are accordingly constructed as steel rings anchored in the concrete.
  • the manholes 171 and 172 are openings left free in the concrete, as is also shown in FIG. 8.
  • centring of the intermediate rpiece 12 in relation to the housing parts 31 and 32 could be effected by means of the cylindrical surface extending coaxially with the machine axis, such centring could be effected by means of centring pins provided in the flange connection, which would result in smaller clearance between the intermediate piece 12 and housing parts 31, 32.
  • the planes of separation 10, 11 of the flange connections could be slightly inclined to each other instead of being parallel, that is to say they could be made divergent in the removal direction.
  • the intermediate piece 12 is very short, despite the many parts situated inside it.
  • the rotor 41 may be wedged to the stator 42, and the stator-side end of the shaft part ⁇ 82 remaining in the housing part 32 may be supported by means of an assembly bearing.
  • the tie rods 18 indicated in FIGS. l and 9, may be omitted. Apart from the two ribs 16, 17, there are no fittings in the operating water duct in the region of the electrical machine 4.
  • a hydroelectric machine set arranged in said duct and comprising a hydraulic machine having a runner, an electric machine having a stator and a rotor, a shaft carrying in overhung fashion at its one end the runner of said hydraulic machine and at its other end the rotor of said electric machine; at least two bearings for said shaft; a housing enclosing said electric machine, said bearings and part of said shaft; said housing consisting of a front part, an intermediate piece and a runner-side part; said intermediate piece containing the electric machine and a portion of said shaft with one of said bearings and being separable from said front part and said runer-side part in planes extending substantially perpendicular to the axis of said shaft; means for rigidly connecting said front housing part as vwell as said runnerside housing part to the walls of said duct; said shaft being detachably connected t0 the remainder of said shaft in the region of said plane of separation between said intermediate piece and
  • said means for rigidly connecting said front housing part as well as said runner-side housing part to the walls of said duct include tie rods being anchored in the walls of said duct, and engaging said housing parts substantially tangentially.
  • said means for rigidly connecting said front housing part as well as said runner-side housing part to the .walls of said duct comprise one under and one upper vertical rib; said under rib connecting the bottom of said housing parts to the walls of said duct; said upper rib having a front portion connecting the top of said front housing part to the walls of said duct, and a runner-side portion connecting the top of said runner-side housing part to the walls of said duct; said front portion and said runner-side portion of said upper rib leaving a space between each other adapted to allow removal of said intermediate piece together with said electric machine and said shaft portion with sai-d bearing, contained therein; said intermediate piece and said under rib leaving another space between each other; guide plates detachably connected to said ribs, limiting said spaces from the room outside the profile of said ribs.
